Object Size Adjustment via Segmented Axis Guides
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of digital devices with display screens face inconvenience in adjusting the size of objects on the screen, as current methods often require multi-stage and cumbersome input procedures.
Innovation Solution
A method and apparatus that recognize objects on the screen, display guides indicating object regions, and allow users to adjust object sizes easily by selecting and resizing along axes using touch or key input commands, with the ability to adjust size in real-time and maintain aspect ratios.

Engineering Contradiction Analysis
1Ease of operation
If traditional multi-stage input procedures are used to adjust object size, then precise control is achieved, but operation complexity increases
Solution Approach 1:
The object size adjustment is segmented into two independent axes (first axis and second axis perpendicular to the first), allowing users to adjust each dimension separately through distinct guide axes. This segmentation simplifies the adjustment process by breaking down the complex 2D resizing operation into manageable 1D adjustments along each axis.
Solution Approach 2:
The patent introduces guide axes that extend beyond the boundaries of the object region, providing external reference lines for size adjustment. By projecting the adjustment guides outward from the object, the interface provides clearer visual cues and more ergonomic control points, transforming the constrained in-object adjustment into an extended external guidance system.
2Adaptability or versatility
If object size adjustment is enabled on limited screen space, then display functionality is enhanced, but available interaction area is reduced
Solution Approach 1:
The guide axes are projected outward from the object region boundaries, utilizing the surrounding screen space for adjustment operations. This external projection allows the adjustment interface to extend into previously unused areas, providing clear visual guides and control points without encroaching on the object display area.
Solution Approach 2:
The guide axes serve as intermediary elements between the object and the adjustment controls. These visual guides mediate the interaction by providing external reference lines that indicate adjustment directions and magnitudes, allowing users to perform size adjustments without direct manipulation of the object itself, thus preserving screen real estate.

AI summary
A method and apparatus for adjusting sizes of objects displayed on a screen are provided. The a method includes recognizing one or more objects appearing on the screen, displaying guides indicating regions of the recognized objects on the screen, receiving a selection command for one of the recognized objects, and adjusting, upon reception of a size adjustment command, a size of the region of the selected object with respect to a first axis of the guide associated with the selected object or a second axis thereof perpendicular to the first axis, and displaying the size-adjusted region.
